Given a pointer to the head of a linked list and a specific position, determine the data value at that position. Count backwards from the tail node. The tail is at postion 0, its parent is at 1 and so on. Example head refers to 3 → 2 → 1 → 0 → NULL positionFromTail = 2 Each of the data values matches its distance from the tail. The value 2 is at the desired position. Function Description Complete the getNode function in the editor below. getNode has the following parameters:

Write a menu-driven program to create an unrolled linked list and retrieve,insert and delete an element from it. You may take liberties with the operationswhile implementing them.
Reverse a singly linked list by changing the pointers of the nodes. The datarepresented by the list should continue to remain in the same nodes of the originallist.For example, given a singly linked list START, as shown in Figure P6.9(a), the listneeds to be reversed, as shown in Figure P6.9(b), by manipulating the links alone.
Given the head of a singly linked list of integers, write the function to arrange the elements such thatall the even numbers are placed after all the odd numbers. The relative order of the odd and eventerms should remain unchanged.Input Format:Elements of linked listOutput Format:Resultant linked listSample Input 1:1 4 5 2Sample Output 1:1 5 4 2Sample Input 2:1 11 3 6 8 0 9Sample Output 2:1 11 3 9 6 8 0 in java
Consider a Single Linked List (SLL) of nodes, where ‘node’ is a type with two fields: integer data and the node type reference ‘next’ that refers to the next node in the list. For each part given below consider the SLL and the code given in the second column. Following the execution of the code, show the resulting list (in the answer box, for each part, use the arrow key to draw the list as: head-----> ? -------> ? --------> ?). List and Java Code a head ⟶ 1⟶ 2⟶ 3⟶ 4⟶ null node ptr=head; node newnode = new node(0); // data=0 head = newnode; newnode.next=ptr; b head ⟶ 1⟶ 2⟶ 3⟶ 4⟶ null node ptr=head; node newnode = new node(6); // data=6 while(ptr.next!=null) { ptr=ptr.next; } ptr.next=newode; c head ⟶ 1⟶ 2⟶ 3⟶ 4⟶ null node ptr=head; ptr=ptr.next; head=ptr;
A linked list is said to contain a cycle if any node is visited more than once while traversing the list. Given a pointer to the head of a linked list, determine if it contains a cycle. If it does, return . Otherwise, return . Example refers to the list of nodes The numbers shown are the node numbers, not their data values. There is no cycle in this list so return . refers to the list of nodes There is a cycle where node 3 points back to node 1, so return . Function Description Complete the has_cycle function in the editor below. It has the following parameter: SinglyLinkedListNode pointer head: a reference to the head of the list Returns int: if there is a cycle or if there is not Note: If the list is empty, will be null. Input Format The code stub reads from stdin and passes the appropriate argument to your function. The custom test cases format will not be described for this question due to its complexity.

Given a pointer to the head of a linked list and a specific position, determine the data value at that position. Count backwards from the tail node. The tail is at postion 0, its parent is at 1 and so on.
Write a function, to be included in a sorted linked list class, called printPosition, that will receive a T parameter and print its position within the list ( position 1 if in first node, position 2 if in second…). If the item is not in the list, specify it in a printing. Consider efficiency.
Write a program in Java to implement a Singly linked list with two fields: String name and Integer Age. a) Then, Program ask user to enter name and age of a student, and add the node in the link list b) Store name and age of 5 students c) Then, traverse the link List to print all the nodes

Implement linked based list and ADTs in Java, fullfilling all conditions listed below Remember to use the code images below for data attributes: A LinkNode structure or class which will have two attributes - a data attribute and a pointer attribute to the next node. The data attribute of the LinkNode should be the Money class of Lab 1. A Singly Linked List class which will be composed of three attributes - a count attribute, a LinkedNode pointer/reference attribute pointing to the start of the list and a LinkedNode pointer/reference attribute pointing to the end of the list. Since this is a class, make sure all these attributes are private. The attribute names for the Node and Linked List are the words in bold in #1 and #2. For the Linked List, implement the most common linked-list behaviors as explained in class - getters/setters/constructors/destructors for the attributes of the class, (a) create new list, (b) add data, (c) delete data, (d) find data, (e) count of data items in…
Implement a function bool moveNthElem(QueueSLL&,int n) that moves a queue element at the specified N position to the front of the queue. For example, assuming a queue with the elements {4,6,8,10} and n=3, the 3rd element which has the value 8 will move to the front of the queue. The updated queue will be {8,4,6,10}. The function may use an additional queue.
